I was going to start a thread reviewing this case but someone beat me to it! The photos do a good job, so I won't post my own unless someone wants them. I'll give a review of it though in this thread.
The quality of this case is top notch. The back of the case, where the galaxy tab 8.9 clips in is a thicker type plastic which offers rigid protection. The flap which covers the screen is a thinner material which I can't place. An extension of the front cover creates a flap, that when closed, uses a magnet to snap in place. The clips which the tablet snaps into come right around the edge to be flush with the plane of the screen. There is a cut out for the power button and headphones, but none for the volume rocker. The left and right edges of the tablet in landscape mode are slightly exposed. The case doesn't add a lot of bulk or weight, offering the minimum material necessary for protection. Maybe not noticed in the photos are two features which help this case out. One is the rubber grips on the bottom to help the case stand the tablet up. The other is a thin strip cutout on the back which allows the end of the flap to support the tablet at about 15 degrees, which makes for the perfect angle for viewing and typing while laying on a desk.
The only problem I can find with the tablet is that when the case is open, the rear facing camera is blocked by the flap. I noticed this complaint in a few reviews on the GT10.1 case and the solution is to rotate the tablet 180 degrees where the cover is dangling down and the camera is at the bottom of the tablet. Problem solved.
My overall impression of the tablet is great. I'm very happy with the case. It's a little pricey, but sometimes you have to pay for quality. The ivory color is sharp; a good change from the sea of black cases out there. All in all I would buy it again. In fact I might be doing just that if my wife wants to trade in her 10.1 GT for the 8.9 because she's jealous of my tablet AND case.
EDIT: To add some high quality photos, since I had them.
